In 1898, the
Salvadoran Army selected a hill in
San Salvador to begin construction of a metal galley, and later a wooden structure, to house soldiers of the Legion of Freedom. In 1918, the army commissioned architect Borromeo Flores to construct
barracks for the soldiers.
Sapote trees grew on the hill the barracks were built on, and it was subsequently named "El Zapote". During the barracks' usage by the army, it served as the operational headquarters for the 1st Artillery Regiment and later the Armed Forces Transmission Support Command. On 16 June 1993, the Salvadoran president
Alfredo Cristiani and minister of national defense
René Emilio Ponce issued Decree Number 65 which transformed the El Zapote barracks into a military museum under the administration of the
Ministry of National Defense. The museum opened to the public on 6 September 2002. On 7 January 2003, the remains of
Manuel José Arce, a Salvadoran politician who served as the first
president of the
Federal Republic of Central America from 1825 to 1829, were interred at the military museum. == Displays ==
